I recently sent out my first campaign letters.  

Owner shared my 'we buy houses' letter with their Realtor.  

They generally have a csv excel list you can just merge with a word document and pump out some personalized letters. http://www.agentlinkus.com/content/reo-bpo-signup-...It is always a good idea to apply and start completing BPO's when aspiring to be an REO Agent.  

By the way, 2 years is a crazy time line, and I'd be suspect of any "approvals" at this point, without actually seeing the approval letter. 

I have my cash buyers list from my county clerks office and I would like to find a simple introductory letter to use as a starting contact.

Or, you can just send them a letter saying you buy houses and would like to discuss the house they own at xxx Main Street. 

This common concept is not workable under Dodd-Frank if applicable, under RESPA, under unilateral contract law, which is what a financing agreement is nor is there a likelihood you'd get a qualified buyer through with a 2 year balloon.

What are method are you using for marketing (call, email, text, letter)?  

When sending out letters for direct mail what size paper and envelope should you use?

My bank does a current interest rate but has a 5 year balloon for restructure ... it just depends on what they do for you.I lived down in Naples for 6 years, so I am very familiar with your market and have sold condos and SFH down there in Ft.
